Beschreibung
Zusammenfassung:	The invention discloses a catalyst for coproduction of synthesis gas prepared gasoline and low carbon olefin and a preparation method of the catalyst. The preparation method of the catalyst comprisesthe following steps that (1) EDTA, EDTA2Na and Fe(NO3)3.9H2O are added into water, a uniform Fe-EDTA-EDTA2Na complexing solution without precipitates is prepared, in the complexing solution, the content of Fe is 10wt% of the weight of a gamma-Al2O3 carrier, and the molar ratio of Fe to the EDTA to the EDTA2Na is 2:1:1; (2) the gamma-Al2O3 carrier is added into the Fe-EDTA-EDTA2Na complexing solution, after uniform mixing, drying is conducted for staying overnight, and thus a solid is obtained; (3) the solid is ground into powder; and (4) the powder is roasted for 4-6 h at the temperature of 500-600 DEG C, and thus Fe-Na/gamma-Al2O3 powder is obtained. The catalyst for coproduction of the synthesis gas prepared gasoline and the low carbon olefin and the preparation method of the catalyst have the beneficial effects
